I will endorse the exquisitely fragrant Hesperocallis undulata - desert
lily. One does not see it in nurseries or gardens. I have tried it from
seed obtained from Aqua Fria Nursery with germination success, but I
believe it needs to be grown indoors or in a heated greenhouse. I have
seen it in Arizona's Death Valley along the road in April. The
trumpet-shaped flower has a white interior with gray-backed petals. As
beautiful as it is fragrant.
